Title:
SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/225525
Kind Code:
A1
Abstract:
Provided is a sensor system with which it is possible to perform ultrasonic examination of wall thinning, cracking, etc., of a pipe or container covered by a thick-walled cover member, without removing the cover member. This sensor system (1), which is used in non-destructive examination, has: a sensor (20) attached to the surface of an object to be examined (42); a sensor coil (21) electrically connected to the sensor (20) by a first cable (22); a first electromagnetic-wave-shielding member (23) arranged between the surface of the object to be examined (42) and the sensor coil (21); a sensor-side coil (3) arranged so as to face the sensor coil (21) across a gap, the sensor-side coil (3) being capable of coupling by electromagnetic inductance; and a probe-side coil (2) arranged so as to be set apart from the sensor-side coil (3), the probe-side coil (2) being electrically connected by a second cable (4).
